In examples above the network was retrained on the image in the left column (marked as training image) The external adaptation is useful when the input image deviates from the statistics of the training images. In these cases,ĭenoising results are boosted dramatically, surpassing known supervised deep-denoisers.

In cases of images deviating from the natural image statistics, or in situations in which the incoming image exhibits stronger inner-structure.

We present a technique for updating the network for better treating the incoming image. PSNR = 26.98dB PSNR = 27.81dB PSNR = 27.41dB PSNR = 27.79dB Instant Adaptation Of trained parameters (garyscale images, σ = 25) Color denoising performance on BSD68 image set Noise Levelīest PSNR marked in bold. Their number of trained parameters shows that our networks, both LIDIA and LIDIA-S (LIDIA small),Īchieve the best results among the lightweight networks.Ĭomparing denoising networks: PSNR performance vs. Our network achieves near-SOTA results while using a very small number of parameters to be tuned.Ĭomparison between our algorithm and leading alternative ones by presenting their PSNR versus The proposed scheme includes a multi-scale treatment, fusing the processing of corresponding patches from different scales. The final reconstructed image is obtained by combining these restored patches via averaging.
LIGHTWRIGHT NOISE PATCH
Our proposed method extracts all possible overlapping patches of size √n × √n from the processed image Īugment the patches with their nearest neighbors and cleans each patch in a similar way.
